We check the fit of your saddle with the thermo sensitive "Impression Pad". The pad will be placed on your horse's back beneath the saddle. Then you have to go for a ride... that's it! When you remove the saddle, you will have an exact impression of how that saddle fits that horse, with that rider. Advantages: You will see if your saddle fits right away. The results will be documented and handed out to you. Please refer any requests to horsetack@online.ms or +49-160-98586469.
